After doing a connect_nonblock then it appears that IO.select will always return immediately and indicate the socket is not writable, when it should instead block and eventually return that it is writable, assuming the connection succeeds.
Example below. Note that this does not appear to be a timing specific issue; the sleep 5 gives it plenty of time to connect, and the select does not wait for the timeout before returning. Presumably calling connect_nonblock again updates some state that was out of sync.
>> addrinfo = ::Socket::getaddrinfo(@host, @port).first
=> ["AF_INET", 80, "pz-in-f99.1e100.net", "22.214.171.124", 2, 2, 17]
>> @handle = ::Socket.new(addrinfo, ::Socket::SOCK_STREAM, 0)
>> sockaddr = ::Socket.sockaddr_in(addrinfo, addrinfo)
